I was forced to question my enjoyment of the bus campaigns when I read of the driver who refused to drive a bus with an atheist poster on the side. This wouldn't be the kind of poster that worried me. But for one driver this was a matter of conscience so serious that he was prepared to risk his job.

Are there posters that would cause Quakers similar concern? How about a bus which carried an advertisement urging young people to join the army? Would a Quaker bus driver have problems with that or would the driver decide that it was more important to get passengers to their destinations?
